APPLICATIONS
The abbreviation RT identifies a series of burners for
radiant tube combustion systems. This type of process
consists of using a stainless steel tube to exploit the use-
ful effect derived from heat exchange through the irradia-
tion mechanism. To achieve this, it is necessary to con-
nect the pipe to a burner. The radiant tubes can have dif-
ferent shapes, the most common are "I", "U", "W" or "M",
"double P".

DESCRIPTION
The main characteristic of RT burners consists in double
air mixing. The primary air is mixed on the cross-flow
head developing a twisting flame; the secondary air, gua-
ranteed by special holes placed on the flame arrester
pipe, completes the mixing by extending the flame itself.
This type of device ensures less wear of the initial part of
the radiating tube, normally more stressed, and allows
the maximum heat exchange of the radiant tube flame;
more efficiency and long life of the radiant tube follows.

The calibration of the RT series burners is simplified by
pressure taps that allow to identify the gas and air flow
rates; the volumetric air/gas ratios normally used in
radiant tube burners are 12:1, 13:1. The radiant tube bur-
ners of the RT series can work with cold air and, using
special smooth or finned exchangers with preheated air
up to 500°C, allowing energy savings calculated around
25-30%.
The RT burners are ignited mainly by high voltage
discharge supplied by an EN or WAND series electrode.
Flame detection takes place through a special EN or
WAND series electrode and the UV-2 series ultraviolet
photocell can always be used on request. The flame con-
trols are strongly recommended in all plants operating at
temperatures below 750°C.

WARNINGS
¾¾ The ignition of the RT burners must always be perfor-med at minimum power, and then modulated towards
the maximum, facilitating the ignition and reducing the
output overpressures. It is therefore advisable to use
slow opening solenoid valves on the fuel.
¾¾ The transition from minimum to maximum power, andvice versa, must be gradual and not instantaneous. In
this regard, MRBV regulating valves (data sheet E1302)
are recommended for two-stage adjustments.
¾¾ For all low temperature applications (up to 750°C), theignition of the burner and the control of the fuel gas sole-
noid valves must be carried out using a certified burner
control device.
¾¾ To avoid any damage to the burners, make sure thatthe blower does not send them stale air from combustion
products, oils, solvents or other. To prevent these pheno-
mena from occurring, possibly install the blower or the
suction pipe outside the building and away from the
exhaust ducts.
¾¾ Check the correct connection of the power lines afterinstallation. Before lighting the burner, check that the
combustion air and fuel gas pressure values are correct
(page 05).
¾¾The burner can only work in the indicated powerrange. Operation with reduced or excessive power can
compromise the efficiency and life-span of the burner. In
this case, the general warranty conditions will automati-
cally expire and ESA-PYRONICS will not be held
responsible for any damage to property or persons.
¾¾ If there are disturbances to other equipment duringthe burner start-up phase, use the connector with anti-
interference filter to connect the HT (High Voltage) cable
to the ignition electrode.
¾¾ Do not carry out close ignitions of the burner in ordernot to overheat the control devices of the ignition system
(solenoid valves and transformers). Consider a mini-
mum time between one ignition and the next equal to the
sum of the prewash time and the first safety time, increa-
sed by at least 5 seconds (in any case, do not perform
more than 2 ignitions in a period of 30 seconds).
¾¾ Operate on the burner and connected devices only inthe absence of supply voltage. In case of malfunctio-
ning, follow the instructions in this manual in the
Maintenance chapter, or contact the ESA-PYRONICS
assistance service.
¾¾ Any modification or repair carried out by third partiescan compromise the application safety and automatical-
ly invalidate the general warranty conditions.

INSTALLATION
The RT series burners can be installed in any position,the installation is simplified as the radiator burner-tubefixing flanges can be adapted according to specificneeds.
For the connections of the air and gas pipes to the burnerit is mandatory to use flexible fittings that must compen-sate the expansion of the radiant tube with respect to theattachment flange on the mechanical structure of the fur-nace. The air and gas inlets can be freely rotated through90° and are fitted with threaded or welded ESA Pyronicsflanges.
For installation, carefully follow the instructions below:
1 - Place the RT burners away from heat sources andproducts such as: liquids, solvents or corrosive gases.
2 - Make sure that the dimensions of the radiant tube andthe distances of the supply pipes correspond to what isspecified in the "overall dimensions".
3 - Assemble the burner on the radiant pipe connectionflange corresponding to the position reserved for the bur-ner (refer to the construction drawing of the radiant pipeitself.) Place a gasket made of fibro-ceramic material bet-ween the flange of the burner and that of the radiant tube(pos.01) Use stainless steel screws (pos.02) taking careto lubricate the screw threads with adequate high tempe-rature lubricant.
4 - Connect the combustion air and fuel gas inlet pipes,adequately protecting the sensitive parts of these linesfrom the exhaust pipe coming out from the radiant tube.If using a radiant tube equipped with a recuperator, con-nect the preheated air outlet to the combustion air inlet ofthe burner using a stainless steel compensation joint withsuitable temperature-resistant gaskets.
5 - Make the electrical connections to the ignition anddetection electrodes (or to the UV photocell where provi-ded), taking care to make the conductors pass far awayfrom heat sources.
6 - Make sure that the burner body and all connectedmetal elements are connected to the system groundingwith appropriate conductors.
7 - The connection cable from the ignition transformer tothe electrode must be specific for high voltage andunshielded. The length should not exceed about onemeter; otherwise the ignition transformer must be positio-ned near the burner. The HV cable must be laid awayfrom power cables and not in metal conduits, ideally itshould be left in the open air.
8 - For more details, see the technical data sheet for igni-tion transformers.

IGNITION - SETTING
The operations indicated in the following chapter must be
performed by expert or qualified technical personnel.
Failure to follow the instructions can generate dangerous
conditions.
1 - Check that the combustion air pressure at the outlet of
the blower and of the fuel gas supply are in the permitted
range.
2 - Adjust the working and intervention pressures of the
combustion system safety devices, whether they are sin-
gle burner or general for the combustion system, such as:
gas pressure reducer, blocking valve, relief valve, pressu-
re switches, etc. Simulate the intervention of all the safe-
ty devices, including the intervention of the safety high
temperature, verifying that the fuel blocking devices act
correctly.
3 - Position the motorized air regulation valve in the maxi-
mum opening position and adjust, through the gate val-
ves, the air pressures entering the burner, referring to the
values indicated in the "Burner Performance" chapter for
maximum capacity (page 06).
4 - Position the motorized air regulation valve in the mini-
mum opening position and adjust the opening of the same
to obtain (at the input to the burner and the ejector) the
pressures relative to the minimum power.
5 - Activate the burner control device and perform a few
ignition attempts until the burner ignites. During the igni-
tion attempts, act on the gas control valve and, starting
from the fully closed position, open it gradually until the
burner ignites.
6 - Position the motorized air regulation valve at the maxi-
mum opening and adjust, through the gas regulation
valve, the maximum fuel flow rate, checking the differen-
tial pressure created on the calibrated gas flange.
7 - Check again that, at minimum and maximum power,
the air input pressure to the burner corresponds to what
is indicated in the "Capacity parameters" chapter. It is
possible that, with the burner on, they are different com-
pared with when the burner is off.
8 - Perform repeated ignition attempts at the minimum
power of the burners, with maximum temperature ranges,
to verify the reliability of the ignition and the flame stabili-
ty during the adjustment.
9 - Carry out an analysis of the combustion fumes with a
suitable analyzer. The oxygen value must comply with the
following adjustment ranges:
Maximum capacity: O2 3÷4%
Minimum capacity: O2 6÷8%
PREMIX AIR FLOW SETTING WHERE SCHEDULED (LPG BURNERS)
The premix line is supplied with the LPG burners. The
calibration must be performed with the burner off and in
minimum flow conditions. The premix line must be powe-
red by an outlet necessarily located upstream of the air
flow control valve, whether it is in the area or controlled
by the single burner.
1. Position the burner in conditions of minimum combu-
stion air flow.
2. Open the premix air cock.
3. Adjust the micrometric needle valve according to the
following indications:
4. In any case, check that at minimum capacity the bur-
ner does not create carbon black on the combustion head
and on the electrodes. If necessary, increase the premix
air setting.
RT-1: Gas body pressure = 2 mbar
RT-2: Gas body pressure = 2 mbar
RT-3: Gas body pressure = 2 mbar
RT-4: Gas body pressure = 2 mbar
RT-5: Gas body pressure = 2 mbar

For correct dismantling and better maintenance of the RT
burners, carefully follow the instructions below with the
system switched off.
BURNER LOCKOUT
For correct dismantling and better maintenance of
the RT burners, carefully follow the instructions
below with the plant switched off. In burner lockout
conditions, refer to the burner control device indica-
tions and to the relative manual to identify the cause.
The main cases are shown below:
¾¾Illegal flame detection: Lockout due to the detection
of an illegal flame signal during the phases preceding
ignition or after they go off. The causes are to be found
in the detection system (faulty probe or humidity), or in a
gas leakage from the safety solenoid valve that allows
the burner to remain on.
EXTRAORDINARY MAINTENANCE
¾¾Ignition failed: Lockout due to lack of flame formation
during start-up. The causes are to be found in the igni-
tion system (absence of spark, broken electrodes or not
in the correct position), in poor regulation of fuel and
combustion flow or in the detection system (faulty probe
or interrupted cables). Specifically, in the first two cases
the flame does not ignite, while in the last case the flame
is formed but the burner control device is not able to
detect it.
¾¾Loss of flame signal: Lockout due to the loss of the
flame signal during normal burner operation. The causes
are to be found in the regulation of combustion air and
fuel flow (rapid variations in flows, regulation out of per-
mitted range) or in the detection system (faulty, dirty or
badly positioned probes).
